Detail Preserving Anosotropic Diffusion for Speckle Filtering (DPAD)
DPAD implements two different anisitropic diffusion based schemes for speckle filtering:
-SRAD (Speckle Reducing AD)
-DPAD (detail Preserving AD)
Both methods are based on an anisotropic extension of Frost's and Kuan's LMMSE filters for multiplicative noise. The goodness of the filter is based on a proper estimation of the Coefficient of variation of noise.
The diffusion can also be done using an AOS operator that implements the semi-implicit scheme.
